Lightning Round: I want this to go lower

It's that time again! The Lightning Round bell has rung, and Jim Cramer gives his take on a few favorite audience stocks:

American International Group: "That has kept a lid on the stock, there is absolutely no doubt. As long as that lawsuit is out there, people are going to think that there is going to be a big hit to AIG. I do not think that is the case, but there are plenty of people to who disagree with me."

Ambarella: "Everyone is just worried about the GoPro secondary, which they think will bring the stock down, which then translates into the negative numbers for Ambarella. I think you have to keep your pallet dry until we see how much stock is sold on the secondary."

Marathon Petroleum Corp: "Everyone has now turned on refiners. Why? because they believe that there has been a lot of international refinery capacity that has opened up and will squeeze the margins. I say you have to stay away until that thing is debunked. I don't want to get ahead of that negative story."

Inifinity Pharmaceuticals: "This stock took a big hit today. I don't know why, so therefore I'm not going to cuff it and tell you that I think it's just some sort of jitters. Let me do some work and I will come back on this."

WhiteWave Food Corp: "I like WhiteWave. I would buy half right now, and then let it come in because the market looks ugly."

Sturm, Ruger & Company: "I like Taser. And if Taser comes back down than that's the one we will be in."

Magellan Midstream Partners: "It's been the best one in the group, frankly, and I think it's because of Mike Mears. That said, we are going to need yield support and will need to wait until it comes down a bit more. But this is a good one to own because they are not as exposed."

Weatherford International: "These oil service companies still have further to fall, and some of them - including this one - have now exceeded where I think the downside is. But people have given up and I want that stock to go lower."
